Application led .Tune .22, 1908. Serial No. 489,884.

To all whom t may 1 Be it known that I, ARTHUR E.`VH`I`TNEY, a citizen of the United States of America, and a resident of Winchester, in the' county of Middlesex and Sta-te of Massachusetts, have invented certain new and useful Improvenients in Supplemental Wheels for.

:either in replacin Motor-Cars, of which thel specification. A This invention relates to supplemental wheels for use on motor cars to be used in connection wit-h one of the supporting wheels of the car whenever a puncture or other injury occurs to such Wheel.

any devices have. been constructed for quickly detaching a punctured tire and replacing it with an extra one carried on the car and a variety of devices have been constriicted for repairing the puncture without removing the tire from the wheel. Moreover, in some cases extra wheels are carried which are adapted to replace either oneof the wheels when anyinjury occurs thereto.

It has been found vin practice that when a puncture occurs in the .tire of one of the supporting wheels much` time is consumed the wheel by' another Wheel, removing tie tire and *adjusting an extra one to the wheel, or b` repairing the puncture in the tire Awhile t e tire remains upon the wheel.` f

To avoid these many objections and proy vide a device which will dispense with the necessity of removing the injured wheel from the axle or the punctured tire from the wheel and make it possible to quickly attach a new or supplemental supporting wheel to the one placed out of commission, is the object of the present invention.l

The invention consists in providing an following is a l extra or supplemental wheel which may' be wheels and to besecured to said hu readily stored at any convenient point upon the carriage and lwhich has an annular flanged central portion which'is .adapted to t over the hub of one of the su porting in any well-known manner, the diameter of the extra wheel and that to whichit is attached being the same. A

The invention further consists in certain novel features of construction and arrangement of parts which will be readily understood by reference to the description of the drawings and to the claims hereinafter given. Of the drawings: Figure 1 represents an elevation of the supplemental wheel embodyings.

-10 to said flanges ,wheel the inner face of the ring 10 is' reinthe 'regal ing the features of this invention.' Fig. 2 represents a section of-tliesaine shown secured -toone of the supporting wheels ot' a motor car, and Figs. 3 and 4 represent details of construction to be hereinafter referred to.

Similar characters throughout the several designate like parts figures of the draw- In the drawings, 10 represents a central ring provided with an outwardly extending flange 11, said flange 11 being provided with a Aplurality of bosses 12 to each of which is threaded a vt-ubularvspoke 13 the opposite endof which is threaded to a boss 14 secured by rivets 15 to an annularrim 16 concentric with said ring 10. Secured to the ri/ln 16 in any well-known manner is the usual tire 17. y

'18 represents the hub of one of the supporting wheels mounted upon the axle ,19. and provided with a plurality of radial spokes 20 having at their outer -endsuan ann-ular rim 2l.supporting a tire 22 of'usual construction, the diameter of which is the same as that of thediameter of the tire 17 on the supplement-al wheel.

The flanges 23 'and 23* of the hub 18 are secured together-through lthe spokes 20 by means of bolts 24, the heads of which extend beyond the outer face of the flange 23*. The ring 10 is provided with a plurality of openings 25 of sutlicient size to receive the headsof the -bolts 24when `the supplemental Wheel is placed in position. The flanges 23 and 23* are provided` with a plurality of threaded holes 26 into which are adapted to be threaded the bolts 26* to secure the ring 23 and 23* so that the two wheels will turn together. s

In order to prevent injury to the outer face of the flange 23 when the supplemental wheel is applied to the usual supporting forced by a layer 27 of felt or any other similar soft material. When one of the tires of the usual sup orting wheels becomes punctured, two or t ree` registering studs 28 are inserted into the threadedholes 26 and then the supplemental wheel is placed uion these registering studs which studs exten through the smaller openings 29` in the ring 10. These studs accurately register thev holes 26 and 29 so that they are in perfect al'inement and the supplemental wheel is supported on ar supporting wheel. Through t each of the holes-29 not occupied by a regisl ,28 these studs are removed and replaced by holding bolts 26*. This operation of applying the supplemental wheel to the regular supporting wheel occupies but a fraction of the'time that it would take to remove one of t-hese wheels and replace it with a new one or to replace the punctured tire by la fresh one. It is obvious that this is of great advantage as often it is absolutely essential that no time may be lost on a trip but that the occupant of the car should reach a given destination at a stated time.v Moreover it does away with the necessity of the occupant of the car himself'making repairsto which he is little accustomed, it being apparent that any novice may readily apply the sup- -plemental wheel to the regular supporting wheel while it requires expertskill when a tire becomes punctured to remove it and apply a new one to the supporting rim in a satisfactory manner.

To remove one of the supporting Wheels and replace it with another would require the use of a jack to support the axle at that point while the extra weight of a iifth supporting wheel would be very objectionable. In the present device the supplemental wheel is of skeleton structure comparatively light in weight in comparison with the supportmg wheel to which it is secured but is suihciently rigid when once secured to the flange of the si ipporting wheel lt is believed that from the foregoing the operation of the invention and the many advantages thereof will be fully apparent Without any further description.

Having thus described my invention, l

claim 1 A supplemental wheel for motor cars having a central fianged annular member provided with a cylindrical flange projecting therefrom at right angles to its outer "face, a tire supporting rim, a yieldin tire upon said rim, and a plurality of tu ular spokes between said rim and the ange of said annular member and rigidly secured to said rim and ange, said annular member being provided with means for securing it to one of the'supporting wheels of the car.`

2. A supplemental wheel for motor cars having a central annular flanged member, said ange being provided witha plurality of bosses, a spoke threaded to each of said bosses, a tire supporting rim provided with bosses to each of which oneof said spokes is threaded, and means for securing said annular melnber to one of the supporting wheels of the car. a

3. A supplemental wheel for lmotor cars having a central annular anged member provided Vwith a plurality of openings.

through said member and adapted to register with similar threaded openings througlh the flange of the hub of a supporting whee a tire supporting rim tra plurality of spokes interposed between said rim and flanged member supporting said rim in a dierent plane to sald anged member; and a plurality of bolts extending through the openings in the iange to the hub of one of the supporting wheels of the car.
